Cover letter [PATCH 0/2] vgaarb: Fixes for partial VGA opt-out
I'm trying to add support for VGA arbitration on newer Intel graphics devices. The existing code attempts to do this, but appear to have not been updated since GMCH devices roamed the Earth. On newer devices like Haswell, we can disable VGA memory through an MSR on the device, but we rely on the VGA arbiter to manage VGA IO using the PCI COMMAND register. In trying to unregister legacy VGA memory, I found that the VGA arbiter still wanted to disable both memory and IO on the device and that it forgot to actually program the device to disable IO when the decoding is updated. This series attempts to fix both of those. Thanks,
Alex
